Must have for any balance board, especially if your batteries have short balance plugs. Great value and fast shipping. I was going to make these myself but after looking at my time and material cost I could not come close to what Progressive is selling them for.

This is a great addition for your lipos and life batteries. It makes charging easy, no more dangerous hook-ups on the bench. At the field it makes charging a snap. Must mention Progressive is the best at customer service and shipping was super fast.
